Description

本発明は、特に穿孔ナットを含む自己装着雌型固定要素、密閉された固定部材及びパネル組立材並びに密閉された雌型固定部材及びパネル組立材の形成方法に関する。   The present invention relates to a self-mounting female fixing element including a perforated nut, a sealed fixing member and a panel assembly, and a method for forming a sealed female fixing member and a panel assembly.

冷間ヘッディングにより形成され得る、穿孔ナットを含む自己装着固定要素には多様な種類がある。しかし、そのような雌型固定要素は、通常、金属パネルと、特に自動車及び家電産業により現在使用されているような薄い金属パネルと密閉された結合部を形成しない。さらに、冷間ヘッディングにより形成される穿孔ナットは、通常、オイルパンナットのような多数の用途向けの十分なトルク抵抗を有しない。   There are a wide variety of self-attaching fixation elements including piercing nuts that can be formed by cold heading. However, such female fastening elements typically do not form a hermetic joint with metal panels and in particular with thin metal panels as currently used by the automotive and consumer electronics industries. Furthermore, perforated nuts formed by cold heading typically do not have sufficient torque resistance for many applications such as oil pan nuts.

従来技術は、突出部の環状の端面を通過して延びる孔を有する中央の環状の突出部、突出部を囲み概略平坦の環状の支持面を有する環状のフランジ部、及び突出部を囲むフランジ部の環状の支持面の環状溝を有する、冷間ヘッディングにより形成された自己装着雌型固定要素を含む。この固定部材のパネルへの装着中に、突出部は、開口部を介してパネルに受け入れられ、開口部を囲むパネルの一部は、環状溝に変形される。自己装着雌型要素が穿孔ナットである場合には、突出部は、フランジ部の支持面から突き出し、突出部の端面は、パネルの開口部を穿孔する。また、従来技術は、溝の底部または側壁の凹部及び隆起部を含む種々の回転防止手段を含む。しかし、そのような回転防止手段は、通常、薄い金属パネルには適さず、穿孔ナットは、通常、密閉された結合部を形成しない。   The prior art includes a central annular protrusion having a hole extending through the annular end face of the protrusion, an annular flange having a substantially flat annular support surface surrounding the protrusion, and a flange surrounding the protrusion. A self-fitting female locking element formed by cold heading with an annular groove in the annular support surface. During the mounting of the fixing member to the panel, the protrusion is received by the panel through the opening, and a part of the panel surrounding the opening is transformed into an annular groove. When the self-mounting female element is a piercing nut, the protrusion protrudes from the support surface of the flange, and the end surface of the protrusion pierces the opening of the panel. The prior art also includes various anti-rotation means including recesses and ridges in the bottom or sidewall of the groove. However, such anti-rotation means are usually not suitable for thin metal panels, and piercing nuts usually do not form a sealed connection.

そのため、自己装着雌型固定要素、特に穿孔ナット用の長いフェルトの必要性が存在し、穿孔ナットは、冷間ヘッダー技術により形成され、特に薄い金属パネルとの十分なトルク抵抗を有し、例えばオイルパン等を含む、密閉された結合部を必要とする用途のパネルと密閉された結合部を形成する。本発明の自己装着雌型固定要素、雌型固定要素及びパネル組立材並びに密閉された結合部の形成方法は、従来の冷間ヘッダー技術により形成され得る雌型固定要素にこれらの対象物を形成する。   Therefore, there is a need for long felts for self-fitting female fastening elements, especially piercing nuts, which are formed by cold header technology and have sufficient torque resistance, especially with thin metal panels, for example Form a sealed joint with a panel for applications that require a sealed joint, including oil pans and the like.

上述したように、本発明にかかる自己装着雌型固定要素は、自己穿孔雌型固定部材または穿孔ナットとして使用可能であり、ここで、雌型固定要素は、金属パネルに開口部を形成し、ダイプレスの１ストロークの間に装着される。代替的に、自己装着雌型固定部材は、クリンチナットとして使用可能であり、ここで、クリンチナットは、予備穿孔されたパネル開口部に装備される。また、本発明にかかる自己装着雌型固定要素の望ましい実施形態は、従来の冷間ヘッディング技術により形成可能であるが、特に金属パネル使用時の優れた結合完全性を提供し、以下に説明する図５に図解された本発明の方法により、密閉されたナット及びパネル組立材を提供するために使用され得る。   As described above, the self-attaching female fixing element according to the present invention can be used as a self-piercing female fixing member or a punching nut, wherein the female fixing element forms an opening in a metal panel, Mounted during one stroke of die press. Alternatively, the self-mounting female locking member can be used as a clinch nut, where the clinch nut is mounted on a pre-drilled panel opening. Also, the preferred embodiment of the self-mounting female fixing element according to the present invention can be formed by conventional cold heading techniques, but provides excellent coupling integrity, especially when using metal panels, and will be described below. The method of the present invention illustrated in FIG. 5 can be used to provide a sealed nut and panel assembly.

図１に図解された自己装着雌型固定要素２０は、例えば、離間された平坦部２４を有する円筒体２２と図４に最良に図解される筒状のバレル部２６とを有する。自己装着雌型固定要素は、さらに、環状の端面３０と図示するように好ましくはねじ加工された円筒孔３２とを有する中央の環状の突出部２８を有する。その代わりに、孔は、本発明の自己装着雌型固定部材の適用について以下に述べるような、ねじ成形またはねじロール成形された雄型固定部材またはプラグを受け入れるために、ねじ加工されなくてもよい。雌型固定要素２０は、さらに、突出部２８を囲み平坦な環状の支持面３６を有する環状のフランジ部３４を有する。本発明の自己装着雌型固定要素２０が、穿孔ナットとして使用される場合には、突出部の環状の端面３０は、好ましくは平坦であり、環状の支持面３６は、図３に最良に示すように、端面３０の平面の下方に配置されてもよく、あるいは、平坦な表面が同一平面上にあってもよい。環状の溝３８は、突出部２８に隣接する内側の溝側壁４０を含み、突出部の外壁、外側の溝側壁４２及び底部の溝壁４４も形成するフランジ部３４の支持面３６において規定される。望ましい実施形態では、外側の溝側壁４２は、図３に最良に示すように、内側に底部の溝壁４４から突出部２８に向かって傾斜され、内側の溝側壁４０は、図３に示すように、底部の溝壁４４からフランジ部に向かって外側に傾斜されている。望ましい実施形態では、溝の内側及び外側の側壁の両方は、図３に示すように傾斜されて、パネル上の雌型固定要素の保持力を改善するが、溝の内側の側壁４０は、円筒状であってもよい。傾斜された内側及び外側の側壁４０及び４２は、当業者により場合によっては「再入可能な溝」として参照される環状の溝３８の制限された開口部を形成する。   The self-fitting female locking element 20 illustrated in FIG. 1 has, for example, a cylindrical body 22 having spaced apart flat portions 24 and a cylindrical barrel portion 26 best illustrated in FIG. The self-mounting female locking element further has a central annular protrusion 28 having an annular end face 30 and a cylindrical bore 32 which is preferably threaded as shown. Instead, the hole may not be threaded to accept a threaded or screw roll molded male fastening member or plug, as described below for the application of the self-attaching female fastening member of the present invention. Good. The female locking element 20 further includes an annular flange portion 34 that surrounds the protrusion 28 and has a flat annular support surface 36. When the self-attaching female locking element 20 of the present invention is used as a piercing nut, the annular end surface 30 of the protrusion is preferably flat and the annular support surface 36 is best shown in FIG. Thus, it may be arranged below the plane of the end face 30, or a flat surface may be on the same plane. The annular groove 38 includes an inner groove sidewall 40 adjacent to the protrusion 28 and is defined in the support surface 36 of the flange portion 34 that also forms the outer wall of the protrusion, the outer groove sidewall 42 and the bottom groove wall 44. . In the preferred embodiment, the outer groove sidewall 42 is inclined inwardly from the bottom groove wall 44 to the protrusion 28, as best shown in FIG. 3, and the inner groove sidewall 40 is as shown in FIG. Further, it is inclined outward from the groove wall 44 at the bottom toward the flange. In the preferred embodiment, both the inner and outer side walls of the groove are beveled as shown in FIG. 3 to improve the retention of the female locking element on the panel, while the inner side wall 40 of the groove is cylindrical. It may be a shape. The angled inner and outer sidewalls 40 and 42 form a limited opening in the annular groove 38, sometimes referred to by those skilled in the art as "reentrant groove".

本発明の自己装着雌型固定要素２０の望ましい実施形態では、底部の溝壁４４は、図１及び図２に示すような、くさび形状で周囲に離間された複数の凹部４６を含む。くさび形状の凹部４６は、それぞれ、凹部の底壁４８と対向する凹部側壁５０とを有する。凹部側壁５０は、くさび形状の凹部４６が、フランジ部３４に隣接するより狭く突出部２８に隣接するように、外側に拡がる。望ましい実施形態では、くさび形状の凹部４６の底壁４８は、平坦で、底部の溝壁４４の平面から離れている。図示するように、凹部４６が内側の溝側壁４０から外側の溝側壁４２まで延びる場合には、周囲に離間されたくさび形状の凹部４６は、このため、底部の溝壁４４を中断し、周囲に離間された部分を形成する。代替的な説明は、溝が、周囲に離間された隣接するくさび形状の凹部４６の間に複数の離間された溝の底壁４８を含むということである。   In a preferred embodiment of the self-attaching female locking element 20 of the present invention, the bottom groove wall 44 includes a plurality of recesses 46 that are wedge-shaped and spaced around, as shown in FIGS. Each of the wedge-shaped recesses 46 has a recess side wall 50 facing the bottom wall 48 of the recess. The recess side wall 50 extends outward so that the wedge-shaped recess 46 is adjacent to the protrusion 28 more narrowly adjacent to the flange portion 34. In the preferred embodiment, the bottom wall 48 of the wedge-shaped recess 46 is flat and away from the plane of the bottom groove wall 44. As shown, when the recess 46 extends from the inner groove sidewall 40 to the outer groove sidewall 42, the wedge-shaped recess 46 that is spaced around the periphery thus interrupts the bottom groove wall 44 and Forming a part spaced apart from each other. An alternative explanation is that the groove includes a plurality of spaced groove bottom walls 48 between adjacent wedge-shaped recesses 46 spaced around the periphery.

図１及び図２に示すように、底部の溝壁の部分４４は、隣接するくさび形状の凹部４６の間で、溝の内側の側壁４０と溝の外側の側壁４２とに結合するアーチ形の内側及び外側の部分を除いて、概略矩形である。概略矩形の底部の溝壁の部分４４とくさび形の凹部４６の幾何学的配置は、図２において説明される。図２に示すように、くさび形の凹部４６の間の底部の溝壁４４の部分は、孔３２の軸Ｄから形成される円Ｃに正接し、突出部２８の端面を通る平行線Ａ及びＢにより規定される。図２に示すように、平行線Ａ及びＢは、隣接するくさび形状の凹部４６の凹部側壁５０に一致し、その結果、底部の溝壁４４の部分は、隣接するくさび形の凹部４６の側壁５０により規定される平行線により規定され、周囲に離間された凹部４６の凹部側壁５０は、外側に拡がって概略矩形の底部の壁部分４４の間にくさび形の凹部４６を形成する。しかし、理解されるように、底部の溝壁の部分４４は、実際に、アーチ形の内側及び外側の側壁を有する環の部分である。最も望ましい実施形態では、平坦な底部の溝壁の部分４４とくさび形の周囲に離間された凹部４６とは平坦であり、その結果、凹部の底壁４８は、底部の溝壁４４部分に平行であるが、図示するように、底部の溝壁４４部分の平面より下方に離されている。   As shown in FIGS. 1 and 2, the bottom groove wall portion 44 has an arcuate shape between adjacent wedge-shaped recesses 46 that joins the inner side wall 40 of the groove and the outer side wall 42 of the groove. Except for the inner and outer portions, it is generally rectangular. The geometry of the generally rectangular bottom groove wall portion 44 and the wedge-shaped recess 46 is illustrated in FIG. As shown in FIG. 2, the portion of the bottom groove wall 44 between the wedge-shaped recesses 46 is tangent to a circle C formed from the axis D of the hole 32, and parallel lines A passing through the end face of the protrusion 28 and Defined by B. As shown in FIG. 2, the parallel lines A and B coincide with the recess sidewall 50 of the adjacent wedge-shaped recess 46 so that the bottom groove wall 44 portion is the sidewall of the adjacent wedge-shaped recess 46. The recess sidewalls 50 of the recesses 46, defined by parallel lines defined by 50, are spaced apart and extend outward to form a wedge-shaped recess 46 between the generally rectangular bottom wall portions 44. However, as will be appreciated, the bottom groove wall portion 44 is actually the portion of the annulus having arcuate inner and outer sidewalls. In the most preferred embodiment, the flat bottom groove wall portion 44 and the wedge-shaped circumferentially spaced recess 46 are flat so that the recess bottom wall 48 is parallel to the bottom groove wall 44 portion. However, as shown in the drawing, it is separated below the plane of the groove wall 44 portion at the bottom.

図５は、図１乃至４に図解された自己装着雌型固定要素２０の取付方法または装着方法を図解し、ここで、雌型固定要素２０は、穿孔ナットとして使用される。上述したように、自己装着雌型固定要素２０は、クリンチナットとして使用されてもよく、このとき、装着に先立ってパネル金属が穿孔される。雌型固定要素２０は、図３と同様に図５で断面にて示される。   FIG. 5 illustrates the mounting or mounting method of the self-mounting female locking element 20 illustrated in FIGS. 1-4, wherein the female locking element 20 is used as a piercing nut. As described above, the self-mounting female locking element 20 may be used as a clinch nut, in which case the panel metal is perforated prior to mounting. The female locking element 20 is shown in cross section in FIG. 5 as in FIG.

上述したように、雌型固定要素２０は、図５に示すように、金属パネル５２に装着されて、該パネルと密閉された結合部を形成してもよい。雌型固定要素２０は、通常「ダイボタン」として参照されるダイ部材５４によりパネル５２に装備される。ダイボタン５４は、通常、プレス（図示しない）の下部ダイシューまたはプラテンに装着され、雌型固定要素２０は、上部ダイシュー（図示しない）の取付ヘッド（図示しない）に受け入れられる。しかし、当業者により理解されるように、ダイボタン５４と自己装着雌型固定要素２０の向きは逆転可能である。ダイボタン５４は、通常、パネルのスラグ６０を受け入れる円筒状の開口部５８を有する円筒体部５６を有する。ダイボタンは、さらに、傾斜されたまたは円錐台形状の外側の表面６４と、傾斜された外側の表面６４をダイボタンの端面５８と結合する半径６６とを有する環状のリップ６２を有する。パネル５２は、ダイボタン５４を通る開口部５８の前面端と突出部２８の端面３０の間で穿孔される。次いで、図示するように、環状のリップ６２は、穿孔パネルの開口部５８を囲む環状のパネル部７０を、フランジ部３４の支持面３６の環状の溝３８内に変形する。望ましい実施形態では、自己装着雌型固定要素２０がパネル５２と密閉された結合部を形成する場合には、円筒状の開口部５８の内径は、突出部２８の外径より小さく、その結果、環状の溝３８の傾斜された内壁４０は、非弾性的にかつ永久的に、図５に示すように半径方向外側に及び軸方向に変形されて、一体の環状のビードまたはリップ７２を形成し、該リップは、環状のパネル部７０を環状の溝３８内に閉成し、図５に示すようにパネル部７０を傾斜された内側及び外側の側壁４０及び４２の下方に締結する。装着時には、パネル部７０は、底部の溝壁の部分４４及び凹部の底壁４８に対しても変形されて、凹部側壁５０に接触してくさび形の凹部４６を実質的に充填する。   As described above, as shown in FIG. 5, the female fixing element 20 may be attached to the metal panel 52 to form a sealed portion with the panel. The female locking element 20 is mounted on the panel 52 by a die member 54, commonly referred to as a “die button”. The die button 54 is usually attached to a lower die shoe or platen of a press (not shown), and the female fixing element 20 is received by an attachment head (not shown) of the upper die shoe (not shown). However, as will be appreciated by those skilled in the art, the orientation of the die button 54 and the self-attaching female locking element 20 can be reversed. The die button 54 typically has a cylindrical body portion 56 having a cylindrical opening 58 that receives the slug 60 of the panel. The die button further includes an annular lip 62 having a sloped or frusto-conical outer surface 64 and a radius 66 that couples the sloped outer surface 64 with the end face 58 of the die button. The panel 52 is perforated between the front end of the opening 58 that passes through the die button 54 and the end face 30 of the protrusion 28. Then, as shown, the annular lip 62 transforms the annular panel portion 70 surrounding the perforated panel opening 58 into the annular groove 38 in the support surface 36 of the flange portion 34. In a preferred embodiment, when the self-fitting female locking element 20 forms a sealed connection with the panel 52, the inner diameter of the cylindrical opening 58 is smaller than the outer diameter of the protrusion 28, so that The inclined inner wall 40 of the annular groove 38 is inelastically and permanently deformed radially outward and axially as shown in FIG. 5 to form an integral annular bead or lip 72. The lip closes the annular panel portion 70 in the annular groove 38 and fastens the panel portion 70 below the inclined inner and outer side walls 40 and 42 as shown in FIG. At the time of mounting, the panel portion 70 is also deformed with respect to the groove wall portion 44 at the bottom and the bottom wall 48 of the recess, so as to contact the recess side wall 50 and substantially fill the wedge-shaped recess 46.

このため、図５に図解する雌型固定要素２０とパネル組立材とは、例えば、雌型固定要素とパネルの間の密閉された結合部を必要とする液体を保持する容器用のオイルパンナットまたは栓を含む多数の用途に使用可能な、確実に密閉された雌型固定要素とパネル組立材とを提供する。詳細には、環状のパネル部７０が一体の環状のビード７２により凹部の底部の側壁４８及び５０に対して環状の溝３８内に締結され、ビード７２がパネル部７０を閉成し、環状の溝３８の傾斜された内側及び外側の側壁４０及び４２との完全な接触を確実にして優れた押し離し強さを提供するときには、くさび形の周囲に離間された凹部４６は、パネル５２上での固定要素２０の回転を防止する。望ましい実施形態では、バレル部２６は、フランジ部３４の直径より実質的に小さい直径を有して雌型固定要素の全体重量を減少し、支持表面を提供する。当業者により理解されるように、通常ダイプレス（図示しない）の上部ダイシューに装着される取付ヘッド（図示しない）は、通常、雌型固定要素２０をパネル５２内に移動させるプランジャー７４を有し、ダイボタン５４は、上述した下部ダイシューの固定部材７６に保持される。   Therefore, the female fixing element 20 and the panel assembly illustrated in FIG. 5 are, for example, an oil pan nut for a container that holds a liquid that requires a hermetic joint between the female fixing element and the panel. Or, provide a hermetically sealed female locking element and panel assembly that can be used for a number of applications, including plugs. Specifically, the annular panel portion 70 is fastened in the annular groove 38 to the bottom side walls 48 and 50 of the recess by an integral annular bead 72, and the bead 72 closes the panel portion 70. In order to ensure complete contact with the slanted inner and outer side walls 40 and 42 of the groove 38 to provide excellent push-off strength, the wedge-shaped recess 46 is formed on the panel 52. The rotation of the fixing element 20 is prevented. In a preferred embodiment, the barrel portion 26 has a diameter that is substantially smaller than the diameter of the flange portion 34 to reduce the overall weight of the female locking element and provide a support surface. As will be appreciated by those skilled in the art, a mounting head (not shown) that is typically attached to the upper die shoe of a die press (not shown) typically has a plunger 74 that moves the female locking element 20 into the panel 52. The die button 54 is held by the fixing member 76 of the lower die shoe described above.

当業者により理解されるように、種々の改良が、添付のクレームの範囲で、本発明の自己装着雌型固定要素２０、雌型固定要素の装着方法、及び固定要素並びにパネル組立材になされ得る。例えば、雌型固定要素２０は、パネルの固定部材を必要とする種々の用途に利用可能であり、図５に図解された密閉された固定部材及びパネル組立材に限定されず、ダイボタン５４は、突出部２８を変形して一体の放射状のビードまたはリップ７２を形成し、これは、密閉された雌型固定部材とパネル組立材の望ましい取り付け部であり、結合の改善された完全性を提供する。さらに、固定要素２０の望ましい実施形態は、環状の溝３８の傾斜された内側の側壁４０を有するが、側壁４０は、円筒状であってもよい。円筒体２２の平坦部２４は、孔３２のねじ加工中に固定要素の保持を助けるが、上述したように、特に孔３２がねじ加工されないときには、必要とされない。本発明の雌型固定要素、パネル組立材及び方法の望ましい実施形態を説明したので、本発明は、これから以下のようにクレームされる。   As will be appreciated by those skilled in the art, various improvements may be made to the self-attaching female fastening element 20, the method of attaching the female fastening element, and the fastening element and panel assembly of the present invention within the scope of the appended claims. . For example, the female fastening element 20 can be used in a variety of applications that require a panel fastening member and is not limited to the sealed fastening member and panel assembly illustrated in FIG. The protrusion 28 is deformed to form an integral radial bead or lip 72, which is the preferred attachment of the sealed female locking member and panel assembly and provides improved integrity of the bond To do. Furthermore, although the preferred embodiment of the securing element 20 has an inclined inner side wall 40 of an annular groove 38, the side wall 40 may be cylindrical. The flat portion 24 of the cylindrical body 22 helps retain the securing element during the threading of the hole 32, but as described above, it is not required, especially when the hole 32 is not threaded. Having described preferred embodiments of the female locking element, panel assembly and method of the present invention, the present invention is now claimed as follows.
